A special fact has been pointed out, however, which integrates the whole period. It consists in common (scientific way of the most prominent Polish economists of those years (O. Lange, M. Kalecki and E. Lipiński): from business cycles examination in capitalism to the theory of socialist economy growth and functioning. After a brief presentation of that way for M. Kalecki and E. Lipiński reasons explaining that interesting similarity have been submitted to analysis in the article. Three factors conditioning casually the described situation have been pointed out: essential interdependence between the capitalistic business cycle theory and the theory of socialist economy growth, similarity of social ideas expressed by the authors' connections with Socialist movement as well as pragmatic approach to economic theory.polinfo:eu-repo/semantics/openAccessArtykuł
